SEPARATOR MECHANISM FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 504,954, dated September 12, 1893.

Application filed March 20, 1893. Serial No.466,888- (N0 model.)

To all whom it may concern.-

Be it known that I, EDWARD M. WHI'ITUM, of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Separator Mechanism for Spinning-Machines; and I hereby declare that the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvementsin separators for spinning-machines by which the yarn passing to one spindle is separated from that passing to the adjoining spindle.

The object of the inven'tionis to so construct the actuating-mechanism of a separator that the separator-blades will be constantly in action.

Another object of the invention is to so construct a yarn-separator that while wider blades may be used these may be entirely removed from between the spindles when dotting.

Still another object is to produce a new and effective blade for yarn-separators which will be light and durable.

The invention consists in the combination, with the other portions of a spinning-machine, of the levers by which the separatorshaft is carried, so constructed and arranged that constant upward and downward motion may be imparted thereto, together with the actuating-mechanism for moving the same.

The invention also consists in the manner in which the separator shaft is mounted on the levers, as well as in the construction of the separator-blades, and such other novel features of construction and combination of parts as will hereinafter be more fully described and pointed out in the claims.

Figure 1 represents a front view of portions of a spinning-frame provided with my improved separators. Fig. 2 is a cross-sectional view of portions of the same. Fig. 3 represents a view of the improved separatorblade removed from the machine. Fig. 4 is an enlarged detail view showing the manner in which the separator shaft is mounted on the levers and the stop for preventingthe excessive depression of the blades toward the ring-rail.

Similar numbers of reference designate corresponding parts throughout.

Yarn-separators for spinning-machines are interposed between the bobbins carried on the spindles for the purpose of limiting the ballooning of the yarn as it passes to the bobbins and preventing the yarn passing to one bobbin from interfering with that passing to the bobbins next adjoining; this ballooning of the yarn is most perceptible during the lower part of the wind, the ring-rail being then farthest removed from the threadboard and a greater length of yarn extending between the traveler and the pig-tail. Separator-blades have therefore been constructed and supported to act mainly during the lower wind and to be lifted away from between the spindles during the upper traverse of the ring-rail so that they will not obstruct the traverse of the same. When, however, the yarn breaks during the upper wind, the loose ends are apt to fly against the yarn passing to the adjacent spindles and become entangled therewith. The use of the separator-blades in this portion of the wind is therefore essential, but they must be arranged so as not to interfere with the ringrail either during its traverse or when, by some accident, it sticks on its downward movement. My improvements are designed to overcome these difficulties as well as to provide a novel separator-blade.

In the drawings 5 indicates the bolsterrail, and 6 the lower rail of a spinning-machine, 7 being one of the samsons to which the brackets carrying these rails are secured.

At the upper portion of the machine is the thread-board 8 secured to the beam 9 in which guide-eyes or pig-tails 10-16 are fastened. In bolsters, set into the bolster-rail, arejour' naled spindles 11-11 which are driven by bands passing around a driving-drum and around the spindle-whirls, or in any other usual way. The ring-rail 12 is mounted on the rods 13 which are vertically movable through perforations in the lower rail and bolster-rail and are operated in the usual Wayred s the slee e 1 a pi ot-al y seem d to the sleeve is the downwardly-extending lever 16 the lower end of the same being rigidly secured to the shaft 17 rotatable in bearings secured to the lower rail one of which bearings is e b aring-b o 1 Also rigidly secured to the shaft 17 and extending practically at right angles with the lever 16 is the arm 19 to the outer end of which is pivoted the adjustable actuating rod 20 the upper end of which is furnished with a yoke or slotted bearing, as shown in Figs. 2'and 4, the separator lever 24 being furnished with a stud or pin pivoted in this yoke and readily removable therefrom, so hat h n o n he parat lades a Shaft y he eleased fr m t eetuatihg ed and dropp ack again t he ame n- I s eviden at any uit b num r of the e actuating-devices can be used.

Firmly secured to the upper cross-frame of the Samson 7, and located intermediate the beam n th center of he ep nnihs reme are pendent-brackets 21 having at their lower portions rocker-bearings 22 on which rest one edge of the sq are-shaft and mou ed. at interv ls n this shaf a the a jus able separator-levers 24 furnished at their rear or in: ner ends with counter-weights and having at the forward ends the curved-stops 2 5 Pivo d to th o a p r ns of the senma er-lever a th s r a m 6 n the hppe en s f which i secur he s parato shaft 27 carrying the separator-blades 28.

When in the doffing the separator-blades are t own ba kwa t i app rent t at th separator-sha an la w ll ha a he Ward movement equal to the length of the,

arms 26 as well as the ordinary upward move,- ment.

The separator-blades 28 are stamped from sheet metal and have shanks 29 bent at right angles with the plane of the blades and then turned partially upward, these shanks having perforations in their main portions and curved-arms 30 +-3O for partially engaging a j shaft; from between the arms extends the y 1 wh h s adapted to n e a keyot in the sepa a af as is ndi ated n Fis- 2, the separator-blades being secured to the shaft by o-pa l mp 3 h e t wh c pass hr ugh th "p rfo t ns i the shanks of the blades.

a curv d upper edg 33 adapt d o allo h blades to be hro h k gainst the bea on the upper tr v se a d h d we d yurv ng sha d 3e w ch lim t the n ces a y.

t e eam and cons q n ly mak g the s These blades are shaped, as i shown n h a ing ha of greater length than heretofore} am able to keep them in constant motion. pivoting the levers to the actuating-rod, as is shown in the drawing, (the top of the rod being a yoke to receive a transverse-pin on the lever,) the levers can be readily disconnected from the rods and dropped back against the samson until the separator-shaft comes in conaet h ew th, th ad n age b in that with a short space between the spindles and the roller-beam a wider blade can be used.
